Jib Tunnel, also known as Lateral Passage is one of the entrances into the Gaping Gill cave system, located behind a large boulder in the north bank of Fell Beck adjacent to Gaping Gill Main Shaft. Although short, it leads to Lateral Shaft, a direct descent into Gaping Gill Main Chamber which is a popular caving route, and has had considerable significance in the history of the exploration of Gaping Gill. It lies within the designated Ingleborough Site of Special Scientific Interest.[4]
